"We're concerned about the impact of this order and any proposals that could impose restrictions on Googlers and their families, or that could create barriers to bringing great talent to the US," Google said in a statement seen by USA Today. "We'll continue to make our views on these issues known to leaders in Washington and elsewhere."

The fund — reported to be Google's largest crisis campaign ever — will be awarded to American Civil Liberties Union, Immigrant Legal Resource Center, International Rescue Committee and UNHCR.

The Google campaign was reportedly disclosed in a message sent by Google CEO Sundar Pichai. It was then confirmed by a Google spokeswoman late Sunday.

"We're upset about the impact of this order and any proposals that could impose restrictions on Googlers and their families, or that could create barriers to bringing great talent to the US," he wrote.

"It's painful to see the personal cost of this executive order on our colleagues."

The executive order affects at least 187 Google employees, according to Pichai.
